MEDIUM

Why flagged The package downloads a prebuilt SDK binary (afx-link) from a non-standard, non-whitelisted host (cdn.hush.umceko.com) which could be swapped by an unrelated party, posing a supply-chain risk despite building the main application from source.

Triggered rules

MEDIUM source=() URL on a non-standard host source_untrusted_domain

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
